The uniformity in Bartlein barrels and finish of the bores is second to none.Their rifling machines are so accurate, they can carry the twist rate to the 4th decimal point (example: 11.3642).The process of Single Point Cut Rifling is the most stress free way to rifle a barrel.The twist is exact, where as other forms of rifling can have variances due to the process they use. Also, the bore and groove dimensions are more uniform.

Bartlein pre-laps their barrels before rifling and finish lap the barrel after rifling.There is no need or under any circumstances, should you fire lap or do any other sort of bore polishing to the barrel.Contrary to what others say, a lapped barrel will not wear out earlier vs. an unlapped one.In our experience, Bartlein barrels will typically last longer than a button barrel, etc...
